Secure Mail

MimeKit supports message encryption, decryption, and signing as well as verifying digital signatures with either the S/MIME or OpenPGP standards. It also supports both creating and verifying DKIM-Signatures.

World-Class

High Performance

MimeKit's parser is orders of magnitude faster than any other MIME parser for .NET. Parse gigabytes of mail in mere seconds rather than the 15 minutes or more that it takes with other .NET MIME parser libraries.

MimeKit and MailKit are personal open source projects that I have put thousands of hours into perfecting
by continuously improving the API based on feedback from developers like yourself, writing documentation,
and optimizing with the goal of making them not only the very best email framework for .NET, but the best
email framework for any programming language. I need your help to achieve this.
